BOBBINVHOLDER.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed October 19, 1907. Serial No. 398,251.

To all whom it 'may concern:

Be it known that I, ALONZO E. RHOADEs, a citizen of the United States, and residentof Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Bobbin-Holders, of which. the folaccompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object the production of a bobbin-holder for'supporting a bobbin during the unwinding of the yarn therefrom, the construction and arrangelivered in two different ways according to the desired tension, means being provided whereby one of such ways of delivery can be rendered ino erative when desired.

I have a so so constructed the bobbin-holder that the spent or empty bobbin may be e'ected or discharged without handling by t e attendant.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out lin t ie following claims.

Figure l is a side elevation of a bobbinholder embodying one form of my present invention Fig. 2 is a top plan view thereof; Fi 3 is a front elevation of the bobbinho der, with a bobbin shown supported thereby.

Referring to Fig. 1, the bracket t having attached thereto vthe rest or pan d on which the bobbin C is laid, the upturned arm A forming a part of the bracket, and the forked clamp A provided with a set-screw a, may be and are of substantially well known construction, the clamp A retaining the bobbin-l holder on the supporting-bar BX of the spooler.

The upper end AX of the arm A is shaped to present a transverse shelf a and an upright shoulder'a, Fig. l, and a headed stud a3 is fixed in the part AX extended longitudinally above and parallel to the rest d but at one side, as shown` clearly in Figs. 2 and 3.

Upon this stud I mountan overhead, tilting ceive the fulcrum stud a3, which is thus at one side of the carrier I but upon whichA the carrier may be tilted laterally, for a purpose to be described. As shown the side guard 4 is preferably a flat piece of metal, outwardly curved or iiared at its front end at 6, and longitudinally recessed at its lower edge at 7, Fig. 1, to form a yarn guidewhen the yarn leading from the bobbin is delivered beneath and up outside of the guard, such delivery being adopted when it is desired to impart some tension or drag upon the yarn as 1t is led from the bobbin.

Referring to Figs. 1 and 3 it will be seen that the upper edge of the guard 4 is slightly to be delivered, and in such case there will be no extraneous drag or tension imposed upon the yarn, as will be obvious. Such delivery is employed when the yarn is line or when the ull thereon affords suflicient tension, the ength of the clearance affording the proper traverse as the yarn unwinds from one to the other end of the bobbin.

Inasmuch as it is desirable to govern the spooler tender as to the manner inwhich the yarn is to be delivered I have means to cross or obstruct the c earance when the yarn is to be delivered through the yarn-guide 7. To this end I mount upon the top of the carrier l a block 8 having extended therefrom a finger 9 of suicient length to cross the clearance or passage when the finger is turned'into dotted line position, Figs. 2 and 3, a set-screw 10 holding the block in place and also clamping it in desired position.

The Overseer willset the finger, and when it is in dotted line position the yarn cannot be delivered through the passage or clearance, for said inger will obstruct the traverseof the yarn and break it, so thatvthe attendant will not fail to effect the delivery by means of the yarn-guide 7.

At the side of the carrier opposite the fixed guard 4 I mount a depending, swinging side guard 11, preferably made of Wire and substantially of usual construction, the upper ends 12 of said guard being fulcrumed in suitable bearings in the carrier.

When a spent or empty bobbin is to be discharged or ejected from the bobbin-holder provided the attendant grasps an upturned'lug 13 on the carrier and tilts the latter on the stud 0.3, swinging the fixed guard 4 to the left, Fig. 3, across the rest d, and bringin said guard into engagement with the bobl in.

The bobbin is pushed olil the left hand side of the rest and discharged from the holder without handling by the attendant, the

weight of the carrier and the parts connected thereto returning it to normal position when the lug 13 is released, the shelf a limiting the return movement of the carrier and maintaining it in its normal, operative position.

The shoulder CL2 backs up or supports the rear end of the carrier and the adjacent face of the head 3 of the fixed guard 4, as will be evident from an inspection of Fig. 1.

Changes in details of construction may be made by those skilled in the art without departing from the spirit and scope of my invention as set forth in the claimsv appended hereto.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A bobbin-holder havingV a rest for the bobbin, a carrier mounted above the rest, a side guard for the bobbin pivotally mounted on and depending from the carrier at one side thereof, and a side guard fixedly mounted on the carrier at its opposite side and having its lower edge recessed to form a yarn guide.

2. A bobbin-holder having a rest for the bobbin, a carrier extended longitudinally above the rest, side guards for the bobbin, depending from the carrier, one of said guards being pivotally connected therewith and the other guard being rigidly connected with and laterally offset from the carrier, to leave a clearance through which the yarn may be led' from the bobbin, a yarn-guide at the lower edge of the fixed guard, and a device on the carrier to cross theclearance when the yarn is governed by the yarn-guide.

3. A bobbin-holder having a rest for the bobbin, a carrierextended longitudinally above the rest, side guards for the bobbin, fix-edly and pivotally connected, respectively,

with the carrier, the lixedly connected gu ardv being laterally offset to leave a yarn delivery passage, and means to, cross said passage when the yarn is led from the bobbin around the lower edge of the fixed guard.

4. A bobbin-holder having a rest for the bobbin, a carrier Vextended longitudinally above the rest, a pivotally mounted side guard depending from the carrier at one side, a fixed guard at the opposite side, rigidly connected at its rear end with the carrier to respectively,

leave a longitudinal clearance through which the yarn may be delivered, a yarn guide at the lower edge ofthe fixed guard, and a manually adjustable finger on the carrier adapted to be positioned across the clearance, to prevent delivery of the yarn therethrough.

5. A'bobbin-holder having a rest for thc bobbin, a carrier fulcrumed above the rest to tilt on an axis parallel thereto, depending side guards pivotally and fixedly connected, with the carrier, the fixed guard being offset laterally to leave a clearance for delivery of the yarn, and means to cross the clearance when the yarn is to be delivered under the fixed guard, tilting of the carrier effecting ejectment of the spent bobbin by the fixed guard.

6. A bobbineholder having a rest for the bobbin, a carrier fulcrumed above the rest to tilt Von an axis parallel thereto, depending side guards pivotally and lixedly connected, respectively, with the carrier, the fixed guard being connected at its rear end only with the carrier, to permit delivery of yarn between said guard and the carrier, the lower edge of the fixed guard being recessed longitudinally to form a guide for'delivery of yarn around said guard, and a manually adjustable finger on the carrier to cross the space between the carrier and iixed guard, and prevent delivery of yarn therethrough, tilting of the carrier effectingejectment of the spent bobbin by the fixed guard.

7. A bobbin-holder having a rest for the bobbin, an overhead carrier, side guards for the bobbin, connected with the carrier to leave a longitudinal yarn delivery opening between the carrier and one of the guards, a yarn-guide at the lower edge of said guard, and means to at will prevent delivery of the yarn through said longitudinal opening.

8. A bobbinholder having a rest for the bobbin, an overhead carrier adapted to be tilted laterally, a swinging side guard and a fixed side guard, mounted on theoarrier to leave a yarn delivery opening between it and the fixed guard, and a device on the carrier manually movable in to position to cross and prevent delivery of yarn through such opening, tilting of the carrier acting through a guard to eject a spent bobbin from the rest.

In testimony whereof, l have signed my name to this specification, in the presence of two subscribing witnesses.
